DUMPING-TRUCK.

Specification of Letters Patent.

rate-nted idept. it 11918.

Application filed February 5, 1918. Serial No. 215,470.

To all whom it may concern:

Be it known that I, Cnnisrnxn F. HANGER, a citizen of the United States,residing at (Tleveland, in the county of uyahoga and State of Ohio, haveinvented certain new and useful Improvements in Dumping- Trucks, ofwhich the following is a. specification.

This invention relates to dumping wagons or trucks, and particularly tothat class thereof in which the body is pivoted at its rear end to theframe of the vehicle, and is provided with means to lift the front end tdump the contents of the body.

The object of the present invention is to provide improved means forlifting the body by hand, the arrangement being such that a great.weight may be lifted by one man.

The invention is illustrated in the accompanying drawings in whichFigure 1 is a side elevation of the truck.

Fig. 2 is a perspective View illustrating the lifting gear.

In the drawings, A indicates the truck frame as a whole, and B thetilting body pivoted at 23 to the rear end of the truck. The bodynormally rests on the frame which may be of any proper construction.

The lifting gear includes a crank handle 1 which may be applied to ashaft 2 carrying a pinion 4 in mesh with a gear 6 on a shaft 7 whichcarries a pinion 8 in mesh with a gear 9 on a shaft 10. These parts aresup ported by one of the sills of the frame, and a bracket 3 attachedthereto. The shaftsQ and 7 are short shafts, but the shaft 10 extendsacross the frame, unjier the body.

This shaft 10 has "thereon a pair of pinions 11 and 11 which mesh withgears 12 and 12 on a. shaft 13 which extends across the frame,additional supports forthe shafts 10 and 13 being indicated at C,supported on cross pieces forming part of the frame.

Rigid with the shaft 13 are a pair of arms or levers la and in which areconnected by pivot pins 16 and 16 to rods 15 and which are pivoted tothe brackets 19 secured to the bottom of the body B.

21 is a brake lever having a shoe or face 21 which may be pressed downagainst a hub 5 on the shaft 2. the lever being pivoted at 22 to a pinprojecting from one of the sills of the frame. 20 is a pawl whichengagesthe pinion i to prevent back slip.

In operation. when the shaft 2- is turned in the proper direction, themotion is transmitted 'by the train of gearing to the shaft 13 which isrocked in proper direction to swing the arms 14: and 14 upwardly andlift the body by means of the connecting rods 15 and 15?, therebydumping the wagon. Then by releasing the pawl 20, the body will drop byits own weight, and this action may be delayed by pressing on the brakehandle 21.

The arrangemen of the two cross shafts 10 and 13, and the gearingtherebetween, and the two levers and connecting rods, is such that astrong and effective lifting gear is provided, which will sustain aheavily loaded body in any position to which it may be raised, and withfew and simple parts.

I claim:

In a dumping wagon the combination with a frame having longitudinal sidesills and cross pieces connecting said sills, a tilting body pivotednear its rear end to the rear end of the frame, a shaft extended acrossbetween the sills and under the body and provided with pinions, a secondshaft extended across between the sills and under the body and havinggears in mesh with said pinions, supports on said cross pieces for themiddle portions of said shafts, levers operatively connected between thelast men- I tioned shaft and the under-side of the body, said leversbeing located between said supports and the side sills, and powergearing operatively engag ng the first mentioned shaft.

In testimony whereof I do aflix my signature in presence of twowitnesses.
